Some time ago, my colleague went to Beijing for a business trip. I can't help but ridicule: Do you have to wear a mask after sleeping? Hey, brother, don't forget that humans still have an invention called air purifiers. Many people think of air purifiers when they encounter smog, and some people may feel that the foggy days in their city are not particularly serious, so they don't think they need to buy them. But this is a misunderstanding caused by the promotion of some merchants in the past. Air purifiers are far more than smog, let's see what the air purifiers do.

1. Target harmful microorganisms.

As the temperature gradually rises, the pace of this summer is getting closer and closer. We all know that summer is the season with the most germs and the fastest breeding. Some people with poor resistance can easily develop abdominal pain, diarrhea, skin allergies and other symptoms in the summer. These bacteria that lurk around us not only become allergens, but also cause symptoms of allergies to some people. More importantly, these bacteria are highly susceptible to disease in summer. The air purifier can effectively kill against streptococci, avian influenza, Escherichia coli, Staphylococcus aureus, SARS virus, coronary poison, and flu.

2. Remove inhalable particles.

Air purifiers are the most basic function except particulate matter. Dust, soot, dander, solid sulfide, solid carbide, etc. are all particulate matter. However, these particles are large and small, such as smog as small as 0.25 microns. If the air purifier filter is not dense enough, it will not be able to achieve the purification effect. The beidouyh air purifier H11 filter can filter particles as small as 0.1 micron, and it also ensures strong air output.

3. Eliminate odors.

The air purifier can effectively eliminate the odor generated by chemical reactions such as human breathing, sweat, urine, mildew, and decay. The carcinogens such as formaldehyde, benzene and TVOC released from the decoration of the room. These are all gaseous pollutants, and many air purifiers have done a bad job in this regard. On the one hand, gaseous pollutants are not as easy to purify as particulate matter, and the second is that professional techniques are required to purify gaseous pollutants. When we purchase, we must see the relevant values of gaseous pollutants.

4. Negative ion generator.

Releases negative ions into the air every second, making the air fresh and refreshing, comfortable and pleasant. Negative ions are known as air vitamins with a variety of beneficial effects: negative ions have improved lung function, improve myocardial function, improve sleep, enhance memory, promote metabolism, increase body resistance and bactericidal function.
